Influence of different processing parameters in physical and sensorial properti...
Correia, Paula; Vítor, André; Tenreiro, Marlene; Correia, Ana Cristina; Pinto, António; Barracosa, Paulo; Madanelo, João; Vacas, Marta; Guiné, RaquelIntroduction: Cheese is a classical dairy product, which is strongly judged by its appearance, flavour and texture. Processing parameters that could affect cheese structure play a dominant role upon the features exhibited by the final product. Serra da Estrela cheese is a DOP cheese manufactured from raw ewes’ milk and curdled with thistle flowers aqueous extract. The aim of this study was the evaluation of phy...
Evaluation of phenolic compounds, antioxidante activity and bioavailability in ...
Guiné, Raquel; Pedro, Ana; Barracosa, Paulo; Gonçalves, FernandoThe thistle flower is usually associated to the making of cheese, because it’s responsible for the phenomenon of the coagulation of milk. However, the number of studies about the chemical composition on this plant has risen, in an attempt to understand its health benefits. The objective of this work was to characterize the thistle flower in relation to its antioxidant activity, the composition of phenolic comp...
Effect of drying on the phenolic composition and antioxidant activity of leaves...
Gonçalves, Fernando; Barbosa, Rui; Barracosa, Paulo; Guiné, RaquelIn Portugal, the flowers of Cynara cardunculus L. are traditionally used for the production of cheese “Serra da Estrela”, because they are responsible for the phenomenon of the coagulation of milk. The leaves may be used in diet as teas, soups, stews or salads. The phenolic compounds, such as phenolic acids and flavonoids, have been associated to their potential health benefits.The objective of this work was to...

Pedro, Ana; Barracosa, Paulo; Guiné, Raquel; Gonçalves, FernandoThe thistle is a plant that is associated with the production of cheese, as it is responsible for the phenomenon of coagulation of milk. Lately there has been an increased the number of studies about this plant, related to the chemical composition in order to perceive the benefits for human health. The aim of this study was to characterize the thistle flower in relation to its composition i...
A Biomassa Verde e Lenhosa dos Espaços Urbanos como Fonte Energética para os Ed...
Viana, Helder; Pinto, Nuno; Costa, Daniel; Barracosa, PauloA biomassa gerada pelos espaços verdes urbanos constitui uma fonte de resíduos significativa que, muitas vezes, é direccionada directamente para aterros podendo ser aproveitada para fins energéticos, nomeadamente no aquecimento térmico de alguns edifícios públicos. O presente trabalho apresenta a quantificação da biomassa verde indiferenciada gerada pelos espaços verdes urbanos, depositada nos pontos de reco...
Avaliação do rendimento agro-industrial dos frutos e sementes de cultivares de ...
Barracosa, Paulo; Caetano, Isabel; Batista, MariaA avaliação do rendimento agro-industrial da alfarrobeira no Algarve foi realizada com base em 27 características morfológicas de frutos e sementes de 43 árvores distribuídas por toda a região. A relação entre as características foi estabelecida por uma análise de componentes principais que resultou na separação das árvores em 5 grupos (I-V). Foi estabelecido um modelo de três ...
Analysis of genetic diversity in Portuguese Ceratonia siliqua L. cultivars usin...
Barracosa, Paulo; Lima, M. B.; Cravador, A.Although carob (Ceratonia siliqua L.) is of great economic importance little is still known about the pattern of genetic variation within this species. Morphological characteristics based on 31 fruit and seeds of continuous characters determinant for agro-industrial uses, were compared with RAPD and AFLP markers for assessing genetic distances in 68 accessions of carob trees, from different cultivars, varieties...
Evaluation of fruit and seed diversity and characterization of carob (Ceratonia...
Osório, Júlio; Barracosa, Paulo; Cravador, A.The genetic diversity of 15 carob ( Ceratonia siliqua L.) cultivars located in an experimental field from Algarve (Portugal) was evaluated over 7 years using 12 fruit and seed phenotypic characters, in order to characterize carob cultivars. The values of morphological traits obtained by cultiv ar were compared with those from other countries of the Mediterranean basin. Statistically significant differences were...
Análise às dinâmicas existentes, na defesa da floresta contra incêndios, no con...
Ferreira, Sandra; Viana, Helder; Barracosa, PauloOs incêndios Florestais são um fenómeno próprio de várias regiões, abrangendo aquelas que apresentam clima com características mediterrâneas, como o nosso país. Embora exista unanimidade em considerar a questão dos incêndios florestais, como um problema grave que urge resolver, ou pelo menos minorar, a verdade, é que dadas as suas variadas facetas., nem sempre, os diferentes Intervenientes envolvidos se ...
